Title: Rolling method in hot-charge of continuously cast slab
Inventor: SUZUKI MIKIO
IPC: B21B1/02
Filed: 1999-11-09
Abstract: PROBLEM TO BE SOLVED: To improve the energy saving effect by raising a cast slab temperature at the charging into a heating furnace when a thick steel plate is manufactured from the continuously cast slab with a rolling mill in the hot-charge. SOLUTION: The cast slab 1 having unsolidified phase 2 in the inner part is forcibly cooled in a continuous caster and this surface temperature is lowered to <=500 deg.C and also, kept to <=500 deg.C for >=15 sec. Then, the cast slab is solidified to the center part thereof while recuperating the heat on the surface of the cast slab and thereafter, the high temperature cast slab cut to a prescribed length is charged into the heating furnace, and after heating into a prescribed temperature, the hot-rolling is executed to manufacture the thick steel plate.  At this time, it is desirable to make >=5% unsolidified phase ratio of the cast slab when this is forcibly cooled, to recuperate the heat by keeping the temperature of the cast slab and to forcibly cool the cast slab after passing through a lower straightening zone in the continuous caster in the case of using a vertical and bending type continuous caster.

Title: Data width expanding method
Inventor: KONDO KAZUAKI
IPC: G06F13/14
Filed: 1989-12-07
Abstract: PURPOSE:To expand the data width of an optional address by allocating the same addresses to >=2 registers and selecting one of both registers based on a partial bit of the data corresponding to the allocated address. CONSTITUTION:An address decoder 2 is provided together with the AND gates 5 and 6, a data buffer 3, an inverter 7, an H register 8, and an L register 9. Both registers 8 and 9 are allocated to a single address and then selected via the gates 5 and 6 via the partial bit of data. In other words, the partial bit is changed for selection of both registers and at the same time the data are written twice into the same address. As a result, the data having the desired valid width are held by the registers 8 - 9. Then the data width of an optional address is expanded.

Title: Shaft like member for caulking, method for caulking the same and device therefor
Inventor: KAWANA TAKESHI
IPC: F16C3/02
Filed: 1993-12-17
Abstract: PURPOSE:To improve the perpendicularity of a shaft like member against a caulking surface of a base plate by giving a required plastic deformation in order to obtain the joining strength onto a head of the shaft like member and doing not give the plastic deformation or making it little onto the other part of the shaft like member. CONSTITUTION:When a shaft like member 1 needs the perpendicularity against a functional standard surface 30 of a base plate 2, base plate holding tools 31a, 31b clamp and restrict a part of the functional standard surface 30. In such a way, even if the flatness of the base plate and the bending precision of the base plate are not enough, the perpendicularity for caulking against the functional standard surface 30 can be surely kept. Further, the degradation of precision caused by being unsteady is prevented by restricting the shaft like member 1 and the base plate 2 by clamping the shaft like member 1 with collet chucks and pressurizing the base plate 2 with rollers.

Filed: 1994-12-21
Abstract: PURPOSE: To accurately detect acceleration even when a frequency difference is small by calculating frequency difference based on the pulse of a pulse signal indicating frequency difference and correcting it with a bias frequency. CONSTITUTION: The accelerometer is provided with resonance systems 20A and 20B for vibrating parts 11A and 11B, and when the parts 11A and 11B are deformed by an external force A, an acceleration is obtained based on a difference Δf0 =f1 -f2 between the resonance frequencies f1 and f2 of the systems 20A and 20B. At this time, a frequency calculation part 41 generates a pulse signal indicating the frequency difference Δf0 in a specified measuring time ts, and it measures its pulse interval based on the clock pulse of a clock signal generating part 45, then it calculates the frequency difference Δf0 based on the pulse interval.  A bias correction calculation part 42 inputs the output from the part 41 and output signal ΔfB from a bias generation part 43 and corrects the frequency difference Δf0 with the bias frequency ΔfB so as to calculates an acceleration A. Thus, even when the frequency difference f0 is small, the acceleration can be detected accurately.

Filed: 1988-12-19
Abstract: PURPOSE:To aim at the abatement of pitching in a device and its stability by forming a buoyancy chamber installed in a wave energy utilizer, giving a wave free access to an air chamber and transmitting air in this air chamber to an air turbine, extendedly in the rear. CONSTITUTION:A wave energy utilizer repeats inflow or outflow of a wave 9 by means of its vertical motion to or from an air chamber 2 out of an opening 3, whereby a water surface 13 moves up and down, driving an air turbine 6 and a generator 7. A front buoyancy chamber 1 is extended rearward and a rear buoyance chamber 14 is installed there. With this constitution, since buoyancy chamber length to wavelength is increased from L1 to L, stability is increased as well. In addition, such an effect that the wave tries to tilt the buoyancy chamber is decreased, the extent of pitching is thus reduced. In this connection, the rear buoyancy chamber may be provided with a cylindrical or box type closed chamber, by way of example, separately from the front buoyancy chamber.

Filed: 1989-12-08
Abstract: PURPOSE:To attain an automatic working system where the working program quantity is small and the program change is facilitated by providing a program storage to a robot controller and a robot control means together with a working sequence storage means and a reading means provided to a main controller respectively. CONSTITUTION:A sequence table TBM is stored in a memory of a main controller 100 and a target position number Qi and a basic action pattern number Pi are added for each shift step number (i). The number Qi is related with the concrete XYZ coordinate value via a position table TBC provided to a robot controller 110. The controller 110 also contains a pattern table TBP where the pattern numbers F and G are set opposite in 1:1 to the corresponding working programs PR (FG). The basic action patterns are combined in accordance with the information (e.g., Q2, P2) on the main controller 100 for concretization of various working programs. Thus it is not required to store a series of working programs in a robot controller for each working sequence. As a result, the program quantity is reduced and the change of the sequence is extremely facilitated since the program change is not required in the controller 110.
